trim/n it rmig/ concern E imam-1 that I, WrLLL-nr Guns, Jr,

" ntion relates to a device for inlubricant between the leaves of ring.

the construction. combination and 1 eat of the several parts generally show. in the accompanying drawing and described in the specification, but more parlj; pointed out in the appended claims. 1 the drawing, Figure 1 illustrates a leaf g to which a device of the class ded is attached; Fig. 2 is a sectional r a portion of the device as applied a spring, and Fig. 3 is a perspective view .e 3 hits.

is a well known fact that a vehicle ing consisting of a. number of separate ves likelv to become stilt in use if it is i icated, and particularly is this true wings or springs which have become resent invention is for a device for ring a lubricant between the leaves 1 spring which. by the movement of rap: itse f, and by the movement of rte leaves causes the lubricant not .1. also by the rubbing action of the sprin upon the other, to for a considerable distance 3 of the device. Bv attaching ent of the lowermost leaf the is eii'ectivelv distributed between This device comprises a metal having perforations 7 adiacent the and with an approximately central eaded perforation S to which an oil cup of anv suitable well known construction is attached. A member or Washer 10 of yielding material, such as rubber er, havin a central perforation l1 5s corresponding to the openings late is disposed on the side of the nosite to the oil cup. This device .ressed against the side of a leaf that the member is pressed net the edges of the separate leaves, forming a practically tight outer packing so that the lubricant from the oil cup 9 may be forced into the space formed by the perforation 11, and from there be in troduccd between the leaves of the spring for lubricating it.

In order to secure the device to a spring a U-shaped member 12 with threaded extremities is passed about the spring; and the extremities are inserted through the perforation 7 in the plate and the corresponding perforation in the member 10. Nuts 13 are threaded on the ends oi the member 12 to hold the device securely in position. The action of the spring itself permits the lubricant to be forced between the separate leaves and the sliding action of one spring upon the other spreads he lubricant along them. Since there is more sliding movement at the ends of the leaves than at the center. which is firmly held, the movement of the lubricant will be rather toward the ends than in the other direction and the lubricant will be dis tributed in the proper place to lubricate the springs. Bcsidesnnaking the springs work easier it will do away with the squeaking noises which they frequently emit.

What I claim is: I

.l, A device of the class described comprising: a plate, a perforated piece of pliant material, the perforation of whic mmunicatcs with surfaces to he lubricated, and an oil cup secured to the plate and communicating thcretln'oug'h with the space formed by the perforation.

2. A, device. of the class described comprising a metal plate having a threaded per foration therein, a lubricating cup tl'ireaded in the perforation, a piece of pliant material having a central opening thercthrough adapted to communicate with the perforation in the plate, and means to clamp the plate and the pliant material against the side of a leaf spring, the pliant material bev treinities to clamp the plate and flexible meterial firmly against the side of the spring.

4. A device of. the class described, C0111- prising a perforated metal plate, a lubricatmg cup connected thereto and communicating with theperforation, a piece ofpliant material having a central opening adapted to communicate with the perforation in the plate, and means for clamping the plate'and pliant material against the side of a leaf' spring, the pliant material being interposed between the plate and the spring. I 5. The combination with a spring having a plurality of leaves, of a perforated plate, a piece of flexible material formed with a perforation registering with the perforation of the plate, the perforation of the flexible material being disposed over a number or leaves of the spring at the side thereof, a lubricating cup connected to the plate and communicating with the perforation thereof, and a U-shaped member extending about the spring and securing the plate and flexible of August A. 1).

material to the spring, the flexible zniiitleriai being bound between the plate andf spr ng.

7. The combination with a spring comei prising a plurality of superimposed leaves, of means for confining a body of lubricant against a portion of the edges of the leaves 8. The combination with a springiconii prising a plurality of superimposed leaves,

a of a casing engaging the spring adapted to contain a lubricant and confine the same against a portion'of the edges of the leaves of the spring.

In testimony whereof I have signed Rif name to this specification, in the presence of two subscribingwitnesses, on this fithday 1913. WILLIAM GRUS, Je. W itnesses:
